Cancer is a major cause of mortality and morbidity throughout the world, including the countries of North-East and South-East Asia. Assessment of burden through cancer registration, determination of risk and protective factors, early detection and screening, clinical practice, interventions for example in vaccination, tobacco cessation efforts and palliative care all should be included in comprehensive cancer control programs. The degree to which this is possible naturally depends on the resources available at local, national and international levels. The present review concerns elements of cancer control programs established in China, Taiwan, Korea, and Japan in North-East Asia, Viet Nam, Thailand, Malaysia, and Indonesia as representative larger countries of South-East Asia for comparison, using the published literature as a guide. While major advances have been made, there are still areas which need more attention, especially in South-East Asia, and international cooperation is essential if standard guidelines are to be generated to allow effective cancer control efforts throughout the Far East.

Performing an online health search is a popular activity conducted on the Internet. Research studies from developed countries provide information on source used, type of search performed and devices used to perform the search. However, the same cannot be said about the online health information searching scene in South East Asia. Online health information searching is gaining popularity in South East Asia. Citizens in these countries are turning to the Internet to obtain health information quickly. Current research studies pertaining to online health information searching in South East Asian is limited, particularly relating to search experiences of South East Asian health searchers. Search experience is pertinent as it could deter or encourage the possibility of conducting future health searches. In this research study, a user study was conducted to describe the online search experience of South East Asian health searchers. A face to face interview with 50 participants was conducted. The interview was audio recorded and transcribed verbatim. Results indicate participants have positive and negative search experiences. In some cases, post search outcomes influenced the search experience. Results of this research study contribute to the growing domain of knowledge in relation to online health information searching. Results of this study also provide an understanding pertaining to the search experience of South East Asian online health searchers.

In this study, we compared light-absorption properties of aerosols observed in East and South Asia from black carbon (BC) mass concentration, aerosol scattering (${\sigma}_s$) and absorption (${\sigma}_a$) coefficients measurements at four sites: Korea Climate Observatory-Gosan (KCO-G), Korea Climate Observatory-Anmyeon (KCO-A), Maldives Climate Observatory-Hanimaadhoo (MCO-H) and Nepal Climate Observatory-Pyramid (NCO-P). No significant seasonal variations of BC mass concentration, ${\sigma}_s$ and ${\sigma}_a$, despite of wet removal of aerosols by precipitation in summer, were observed in East Asia, whereas dramatic changes of light-absorbing aerosol properties were observed in South Asia between dry and wet monsoon periods. Although BC mass concentration in East Asia is generally higher than that observed in South Asia, BC mass concentration at MCO-H during winter dry monsoon is similar to that of East Asia. The observed solar absorption efficiency (${\alpha}$) at 550 nm, where ${\alpha}={\sigma}_a/({\sigma}_s+{\sigma}_a)$, at KCO-G and KCO-A is higher than that in MCO-H due to large portions of BC emission from fossil fuel combustion. Interestingly, ${\alpha}$ at NCO-P is 0.14, which is two times great than that in MCO-H and is about 40% higher than that in East Asia, though BC mass concentration at NCO-P is the lowest among four sites. Consistently, the highest elemental carbon to sulphate ratio is found at NCO-P.

This study evaluates the performance of the Weather Research and Forecasting (WRF) model in reproducing the present-day (1981~2005) precipitation over Far East Asia and South Korea. The WRF model is configured with 25-km horizontal resolution within the context of the COordinated Regional climate Downscaling Experiment (CORDEX) - East Asia Phase 2. The initial and lateral boundary forcing for the WRF simulation are derived from European Centre for Medium-Range Weather Forecast Interim reanalysis. According to our results, WRF model shows a reasonable performance to reproduce the features of precipitation, such as seasonal climatology, annual and inter-annual variabilities, seasonal march of monsoon rainfall and extreme precipitation. In spite of such model's ability to simulate major features of precipitation, systematic biases are found in the downscaled simulation in some sub-regions and seasons. In particular, the WRF model systematically tends to overestimate (underestimate) precipitation over Far East Asia (South Korea), and relatively large biases are evident during the summer season. In terms of inter-annual variability, WRF shows an overall smaller (larger) standard deviation in the Far East Asia (South Korea) compared to observation. In addition, WRF overestimates the frequency and amount of weak precipitation, but underestimates those of heavy precipitation. Also, the number of wet days, the precipitation intensity above the 95 percentile, and consecutive wet days (consecutive dry days) are overestimated (underestimated) over eastern (western) part of South Korea. The results of this study can be used as reference data when providing information about projections of fine-scale climate change over East Asia.

Purpose: This study compares Korean and Chinese consumers on the impact of customer equity on trust. Although there have been many studies regarding the impact of customer equity, most of them are limited to the retail and banking industry and mostly compare East and West cultures. Therefore, this study compares Korea and China within East Asia in the hotel industry. Research design, data and methodology: Based on reviews in the literature, this study explores different effects of customer equity on brand trust between Korea and China. To confirm the hypotheses, the research collected survey data from 186 Korean and 155 Chinese respondents. After confirming reliability and validity of measures, this study conducted a multiple regression to test proposed hypotheses. Results: The results of the study showed that all of three customer equities influences on trust positively in the hotel industry. Regarding comparing Korea and China, brand equity has stronger impact on trust in Chinese customers than South Korean customers, on the other hand, value equity and relationship equity had a slightly stronger positive effect in South Korea than in China. Conclusions: This study found significant differences between Korean and Chinese customers in the hotel industry. These results show that even two countries in the same region of East Asia, South Korea and China, are different. Also, this finding suggests that hotel management level should consider differentiating their marketing strategies for Korean and Chinese customers.

From 1959 to 1984, over 93,000 Koreans moved to North Korea from Japan as part of a repatriation project conducted during this time. Among them were people who had escaped from North Korea and immigrated to Japan and South Korea as well as the descendants of such people. This research examines the immigration trajectories of North Korean defectors related to the repatriation project and its effects on international relations in East Asia in a migration systems context. Specifically, it focuses on 26 North Korean defectors who have connections with Japan and settled in Japan and South Korea. It argues that the migration pathways of North Korean defectors linked with the repatriation project have been constructed with the cooperation of and amidst conflict between East Asian countries. To respond to the situation, North Korean defectors used their connections with Japan in amicable relations between Japan and China. However, after the relations went sour, defectors turned to informal transitional networks. If these strategies were unavailable, the defectors faced difficulties, unless they received social or capital support from the destination countries. After entering the destination country, those who settled in Japan have experienced different situations due to the inconsistency in administrative proceedings, while those in South Korea have been treated equally as other defectors. In this sense, some defectors have faced precarious situations in their immigration.

The aim of the present study is to investigate the interannual variabilities of the East Asia monsoon rainfall associated with the global sea surface temperature anomaly(SSTA). For this study, the summer rainfall(from June to August) over the twenty-eight period of 1961-1988 were analyzed with being divided by nine-subregions over East Asia including Korea, China and Japan. From the analysis of the principal modes explaining the interannual variation, the interannual variabilities of summer rainfalls in South Japan and Korea are larger than those of the other subregions of the East Asia. There is a strong negative correlation between the summer rainfalls of south China and Korea. In this study, the relationship between the summer monsoon of each subregion and SSTs of the tropical NINO regions, of western Pacific warm pool, and of the subtropical ocean were investigated. The longitudinal sections of the lagged cross correlations of the summer rainfal1 anomaly in (a) Korea and (b) south China, and the monthly SSTA in the equatorial(averaged from 65 to 6N) Pacific were analyzed. The negative maximum correlation pattems of Korea''s stammer rainfal1 and SSTs over the eastern Pacific is transfered to positive maximum conrlation over central Pacific region with a biennial periodicity. In South China, the significant positive correlations are found at -12 month lag over the eastern Pacific and maximum negative correlation at 16 month lag over the central Pacific with the quasi-biennial oscillation. But the correlation coefficient reverses completely to that in Korea. In order to investigate the most prevailing interannual variability of rainfall related to the favored SSTA region, the lagged cross correlations between East Asia rainfall and SSTs over the moO regions(NINO 1+2(0-105, 90W-80W), NINO 3(5N-5S, 150W-90W), NINO 4(5N-5S, 160E-l50W) and the western Pacific worm pool (5N-5S, 120E-l60E) were analyzed. Among the lagged cross-correlation cycles in NINO regions, the maximum correlations for the negative lagged months prevail in NINO 1+2 and NINO 3, and the cross correlations for the positive lagged months NINO 4. It is noteworthy that correlation between the western Pacific warm pool SSTA and the monsoon rainfall in Korea and South China have the maximum value at negative 4 month lag. The evolution of the correlation between the East Asia monsoon rainfall and SSTA is linked to the equatorial convective cluster and related to northward propagating situation, and raising the possibility that the East Asia monsoon precipitation may be more fundamentally related to the interaction of intraseasonal oscillations and the sub-regional characteristics including the surface boundary conditions and the behavior of climatological air mass.

Fish killing dinoflagellate Cochlodinium polykrikoides has been separated into four genetically differentiated subpopulations globally based on large-subunit (LSU) ribosomal RNA gene, and two subpopulations have been found in the South Sea, Korea. In this study, distributions of the East Asia and Philippines ribotypes were surveyed in the South Sea for 3 years (2014~2016) using quantitative real-time PCR (qPCR). The East Asia ribotype was detected in all sampling stations of the South Sea (Tongyeong~Wando) by 40~100% positives for 2014~2016, whereas the Philippines ribotype was detected in some areas of Tongyeong~Goheung by 1~2% positives for only 2016 when the Tsushima Warm Current (TWC) was particularly strengthened. These results indicate that the East Asia ribotype is the dominant subpopulation in the South Sea, also some of C. polykrikoides swimming cells might be transported from offshore to the South Sea via TWC.
